I am trying to search a single whole word through a textbox. Say I search "me", I should find all occurrences of the word "me" in the text, but not "memmm" per say.
I am using JavaScript's search('my regex expression') to perform the current search (with no success).
After several proposals to use the \b switches (which don't seem to work) I am posting a revised explanation of my problem:
For some reason this doesn't seem to do the trick. Assume the following JavaScript search text:
var lookup = '\n\n\n\n\n\n2 PC Games \n\n\n\n'; lookup = lookup.trim() ; alert(lookup ); var tttt = 'tttt'; alert((/\b(lookup)\b/g).test(2)); Moving lines is essential

JavaScript match() Function. The string. match() is an inbuilt function in JavaScript used to search a string for a match against any regular expression. If the match is found, then this will return the match as an array.
What is the match() method JavaScript? The string. match() is a built-in function in JavaScript; it is used to search a string, for a match, against a regular expression. If it returns an Array object the match is found, if no match is found a Null value is returned.
Using String. equals() :In Java, string equals() method compares the two given strings based on the data/content of the string. If all the contents of both the strings are same then it returns true. If any character does not match, then it returns false.
To use a dynamic regular expression see my updated code:
new RegExp("\\b" + lookup + "\\b").test(textbox.value) Your specific example is backwards:
alert((/\b(2)\b/g).test(lookup)); Regexpal

Use the word boundary assertion \b:
/\bme\b/ If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
